Suppose dwelling quality is measured on a scale of 1 to 10, and the monthly cost of producing a particular quality equals the square of the quality level: For quality level 1, the cost is $1; for quality level 2, the cost is $4, and so on. The monthly rent equals the price per unit of quality (P= $9)
